Duplicate debits, poor service and poor turnaround! Very bad service!

Very poor service from ADT. Alarm system has been faulty for a year and ADT have continued to deduct monthly direct debits irrespective knowing that my alarm system does not work. Monthly payment made on the 29/04/2019 for R399 and proof of payment sent on the 29/04/2019 to ********** who failed to allocate the payment to my account. ADT take yet another direct debit out on the 09/05/2019 and now send another statement for R399 even though the account has been suspended. Spoke to Tiego Robert Lekoane on the 06/06/2019 who advised a payment of R534.75 must be made for the alarm system to be fixed. I duly made the payment of R534.75 and sent the proof of payment to ********** No engineer booked no action taken. Called ADT again on the 08/06/2019 and spoke to Mpumelelo Mzwakhali who asked for the proff of payment to be sent to him. Sent the proof of payment to ********** He advised he received it and that he cannot assist where ADT customer services is closed on the weekends and I must wait until Monday. Very poor service from ADT - ADT are more interested in taking your money and they do not deliver any service, they do not allocate payments you have made to your account and they are more interested charging customers every month without ensuring customers alarm systems are working!
